A corner pergola maximises the use of space by fitting seamlessly into corners, which are often underutilised areas in outdoor settings. It allows you to create a designated and attractive space for relaxation, entertainment, or dining in an otherwise neglected corner of your yard or garden.

The distinct shape of a corner pergola also adds visual interest to your outdoor space. It creates an eye-catching architectural feature that stands out and enhances the overall aesthetics of your garden or patio.

All of our timber Pergolas, Gazebos, Carports and Porches are fully pressure treated as standard. We take the pre-cut lengths of timber and place them in a large pressure treatment tank, where the timbers are impregnated with a non-toxic preservative. We add a colourant during this process, giving the timber a rich brown colour. By pressure treating the timber, we can offer a genuine 10-year guarantee against rot and insect infestation. We only suggest that you apply a good quality water repellent to prolong the longevity of the timber.

All our Pressure Treated timber is for Use Class 3. It involves the application of preservatives using a vacuum.

The below image is a figurative example of how pressure treatment penetrates wood more effectively than the dip treatment technique which does not penetrate wood in the same way, often only providing a surface coat of treatment and stain. This method therefore offers less resistance to rot and decay.

Pressure treated timbers

Unlike some competitors, we pressure treat our timbers and what is more, we treat only after cutting to ensure no timber ends are left exposed!

A lot of dip-treated sheds require a preservative to be added upon installation or within one year of purchasing their sheds. Ours do not require this, saving you time and money!

 

Unlike our competitors, we only use high-quality spruce timber on our wooden products rather than cheap pine or mixed timber. Why do we use slow grown spruce rather than the much cheaper knotty pine alternatives?

Spruce is considered more stable as it expands and contracts less than pine. This stability means that the spruce timbers in our garden buildings minimise splits from appearing as the timber changes along with the weather.  We responsibly source all our timber, where it grows slowly in the cold northern regions. We all know the old adage of counting the rings to see how old a tree is, well our timber grows slower and takes longer to get to size meaning it has more rings in it. This means it has a tighter grain, and each ring helps prevent cracks and shakes from appearing in the densely packed timber.

Our wooden garden buildings and climbing frames really are built to last therefore we use only the highest quality, slow-grown spruce.  Spruce is much more resilient to warps and splits compared to its cheaper alternative pine. Being a whitewood, it doesn’t discolour anywhere near as much as pine so it is also much more aesthetically pleasing for a garden structure. Considered more stable, less knotty and resinous than pine, spruce will also produce a lot less sap. It is also less dense meaning it is not as susceptible to mould and rot.

Outdoor Living Slow Grown Spruce

Outdoor Living Slow Grown Spruce II

All of the timber in this garden building has been responsibly sourced and pressure-treated to ensure it lasts. Pressure treatment forces the wood preservative into the timber rather than simply dip treating (essentially just covering the exterior) like many companies still do.

Unlike some competition, we can offer a genuine 10-year guarantee against wood-eating fungal and insect infestation on pressure-treated timber.

All our Pressure Treated timber is for Use Class 3.

10 Year Guarantee on Pressure Treated Timber

We use strong 70mm x 70mm posts, made from pressure treated slow-grown spruce in the construction of our stunning Utopia pergola range. Rest assured once the Utopia is secured in place it won’t be going anywhere!

Thick wooden Gazebo posts, Heavy Duty

There’s no need to ‘duck’ on the way in through our quality Utopia wooden pergolas. With a tall walkthrough height you’re free to move in and out of your pergola concussion free. Just what you need when hosting a garden party.

Utopia Pergola Tall Walkthrough Height

This garden building is under 2.5m high. Why does this matter? Under permitted development rights, buildings under 2.5m high can be placed as close as you want to a boundary (eg. a fence line) without planning permission. Garden buildings that are over 2.5m high need to be placed over 2m away from any boundary (eg. a fence line), which could lead to a lot of wasted space. If you want to find out more about permitted development rights see our planning guide

There is nothing more annoying than being in the middle of building something and finding that you don’t have the right fixings to continue. We include all of the screws, nails and fixings that you will need to put your garden building together – not many of our competitors are that thoughtful. This eliminates the need to worry about the type of screws or the length of nails you might need to get started – it’ll all be with your delivery.

Fixings Included

All our garden buildings have been designed on the basis that any competent DIY customer should have no problem installing a product themselves in a short amount of time. You do not have to be an expert at DIY to build a Dunster House garden building, as we do provide you with comprehensive pictorial instructions. We totally understand that DIY is not for everyone therefore, you may want to consider getting in touch with a local carpenter or handyman to install it for you. But before you do, check out our construction video and decide for yourself!

Often, an additional cost is buried within the price when offering finance, thus making your purchase higher priced.

However, we have come up with an alternative method for you where you can use a 0% interest-free credit card to pay off your purchase. For more information, see this article: Do we offer finance?

We use slow-grown Spruce timber to make this Pergola. Spruce is less porous than Pine and so less likely to shrink, warp or split.

Amazing Utopia Diamond Pergola

Smooth communication from ordering our pergola to delivery to our holiday home in North Wales agreeing on a delivery date.
Delivery drivers kept in contact as they got nearer to us and were very friendly.
Our pergola was delivered on a Tuesday morning and we built and finished it by Wednesday evening. Very clear instructions and extremely straight forward to build with two of us.
We have secured it to a pre built decking with post holders and the shape of the pergola has leant itself beautifully to framing an amazing view.
Very pleased with the quality, great value for money.
